While demand in the logistics real estate sector is shifting toward flexible properties with modular spaces, many existing properties remain unused. A revitalization project in Philippsburg demonstrates that the alternative to demolition not only makes ecological sense but can also be economically viable.
A former tire warehouse in Philippsburg was on the verge of being abandoned—no longer usable under building codes and, in practice, impossible to rent out again. In LIST, the owners found a partner that coordinated planning, engineering, and construction under one roof and implemented a comprehensive, turnkey solution.
To make the warehouse fit for future use, firewalls had to be retrofitted. A hybrid structure consisting of reinforced concrete columns was erected; these columns end a few meters below the roof, allowing them to be installed inside the warehouse using, among other things, a crawler crane. This approach proved to be significantly more cost-effective than the originally planned all-steel structure. Fire walls made of precast elements and masonry were then installed between the columns.
All building services were completely renovated: electrical installations, fire alarm system, transformers, and medium-voltage network, along with a new fresh water supply and new sprinkler heads. Gas, water, and electricity meters were distributed across the individual units of the hall and made centrally monitorable. In addition, a new two-story office building was constructed with a seamless connection to the hall, along with comprehensively renovated and expanded restroom facilities.
The standing seam roof, a structure consisting of membrane, insulation, and a metal roof, was retained, as was the facade insulation—both continue to fit well into the building’s design concept.
The surrounding concrete base was re-insulated with Isopanels. At the same time, an installed PV system with over 10 megawatts of capacity complements the sustainability concept—a statement for future-oriented energy supply despite preserving the existing structure.
The location within a water protection area posed another challenge. Over decades, runoff from the metal roof had led to sediment buildup in the infiltration basins. Contaminated topsoil had to be removed and replaced with carbon-rich sand. Additionally, the new outdoor facilities now comply with current KOSTRA requirements: new water treatment systems were installed, and the rainwater retention basins were renovated.
Not every existing property needs to be demolished. With the right combination of vision, technical expertise, and pragmatic implementation from a single source, even seemingly outdated buildings can be transformed into sustainable, flexible, and economically successful properties. These are also more environmentally friendly than any new construction, as “embodied carbon” remains sequestered and significantly fewer gray emissions are generated.
The facts speak for themselves: The project in Philippsburg was highly successful for all parties involved, and long-term leases were signed with prominent tenants—a testament to the concept’s market viability.
